class scippneutron.conversion.beamline.SphericalCoordinates[source]#

A dict with keys ‘two_theta’ and ‘phi’.

Methods

__init__(*args, **kwargs)

clear()

copy()

fromkeys([value])

Create a new dictionary with keys from iterable and values set to value.

get(key[, default])

Return the value for key if key is in the dictionary, else default.

items()

keys()

pop(k[,d])

If the key is not found, return the default if given; otherwise, raise a KeyError.

popitem()

Remove and return a (key, value) pair as a 2-tuple.

setdefault(key[, default])

Insert key with a value of default if key is not in the dictionary.

update([E, ]**F)

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

Attributes

two_theta

Polar angle.

phi

Azimuthal angle.

phi: Variable#

Azimuthal angle.

The angle between the projection of the scattered beam onto the x-y plane and the x-axis.

two_theta: Variable#

Polar angle.

Between the scattered beam and continuation of the incident beam. Mind the factor 2 which is defined as in Bragg’s law.
